Explain components of remote sensing
Satellites can be placed in several types of orbits around Earth. The three common classes of orbits are low-Earth orbit (approximately 160 to 2,000 km above Earth), medium-Earth orbit (approximately 2,000 to 35,500 km above Earth), and high-Earth orbit (above 35,500 km above Earth). Satellites orbiting … See more Electromagnetic energy, produced by the vibration of charged particles, travels in the form of waves through the atmosphere and the vacuum of … See more Sensors, or instruments, aboard satellites and aircraft use the Sun as a source of illumination or provide their own source of illumination, … See more Remote sensing data acquired from instruments aboard satellites require processing before the data are usable by most researchers and applied science users.

WebNov 3, 2024 · Remote Sensing is raster based whereas GIS is vector based. This implies, that the satellite imageries collected through the remote sensing sensors are composed of pixels, but the GIS maps have calculations and are line and shapes based. Another difference is that through GIS, we can georeference the remote sensing satellite … WebInteractions with the Atmosphere. Before radiation used for remote sensing reaches the Earth's surface it has to travel through some distance of the Earth's atmosphere. Particles and gases in the atmosphere can affect the incoming light and radiation. These effects are caused by the mechanisms of scattering and absorption.
